First, I would not recommend trying to kill Ashava on co op on console. I was melee and she was ranged and I couldn’t see shit half the time. Made it really difficult to avoid anything, which brings me to the problem.
If your doing co op you can’t revive after 4 seconds. You have to either wait for your partner to die or someone revive you, which may not be best solution during an world boss fight. I did a later run where I invited someone to party and never had that same limitation, so why is it only there during co op?
Anyway I got it done on one account, which went really smoothly. We had 8 man party with only rogue and sorc and got it done in 7 minutes. Will have to run it again now on her account.
